I recently had issues with my Rheem Pronto 12 so I had it replaced with a Rheem 12. Great decision because it works perfectly. My other Rheem kept having issues but Rheem support did their best to help me out at all times but it was more plumbing related that it didn't last all that long. Very happy with the new unit.

Unit is 5 years old
Works when it wants to
Error 11 code keeps showing
Contacted Rheem on 4 occasions
To no help at all send technician no one shows
Just going to change to a Rinnai
Must be a problem unit if other people showing up with same codes

Please ban Rheem from answering questions in this forum... No hot water and the temp of the (cold) water flashes up instead of the preset temperature. Last time I called Rheem, they got a plumber out and it miraculously started working as he arrived. He still did some "troubleshooting" for 45min which cost me dearly. Should I reset? Turn on the water with the terminal turned off?

Hi...
Our hot water system not working since 1and half months even after the visit by plumbers advised for the whole unit change for the amount of $1400 after discount due service delay. Please advise if it is so expensive.?

Runs off bottle gas, 8 years old. We have to turn water on/off dozen times before it starts. Plumbers don't know how to fix it. Anyone know how to fix ?

This system wont work in the daytime when the sun shines on it. I can't find a plumber who has any clue how to fix it. I would love to know the secret for why this fault exists. I have replaced the power point outside and the gas pressure has been increased but still no luck and no hot water unless its dark outside.

I had a continuous flow installed in beach house, average in terms of reliability but thought I’d update the copper at farm and have had nothing but trouble. Takes at least 2 minutes to start heating, very unreliable, farm is in alpine region so walking out to reset not much fun in sub zero temperatures. This unit has barely been used however has been nothing but trouble since installed and rheem dont stand by products. Avoid, avoid, avoid!

The capacity is good, but it’s not hot. The shower temp in morning is ok, not hot, but at night it is at best Luke warm. Plumber tells me it is working to spec but if this is spec then sorry but I would not recommend it. Rather frustrated and disappointed.

Our Rheem 27 876 series does not deliver hot water. It is not hot enough to take a bath, wash the dishes or do the laundry. It also takes so long for the hot water to come through which wastes water. It doesn't feel like it is 50 degrees which is stated as being the factory setting. We moved into a new build in November 2017 and tolerated the lack of temperature through summer but we are feeling the effects now it is winter.
I am not happy with this Rheem hot water system.

Agreed with the other 1 star posts - this item should not be available for sale as it does not do what it purports to do. With the intention of having hot water on demand as an environmental choice, it negates any energy saving benefit with an agregious waste of water - which I hear is a pretty precious commodity in Australia. The unit is mounted on the back wall of our main floor powder room, and I have yet to wash my hands with anything resembling hot water. Taking a shower results it running it for 90 seconds on full hot before it warms, then you get peaks and valleys of varrying degrees of water, the warmest lasting for only 20 seconds. There should be a recall on these Australia wide.

Got our house built with this system. I have been continually frustrated about the amount of water wasted waiting for the hot water to come on! Half a bucket of water actually! No wonder my water bill is so high with the amount of water wasted! Imagine that amount being water every time we take a shower or I want to hand wash a few dishes! Please do not buy this product thinking you will be saving money.

Don’t want to waste anymore money getting a plumber to check if this can be fixed. Shame on a new home. Next time I am researching every product before agreeing to purchase.

Have been happy with the unit since we moved in. No issues with the unit itself. Unfortunately it was Rheem customer service we found disappointing. We would have had to wait 4 days for a repair with Rheem. We had hoped for a better response considering the cold winter weather & our young family. We ended up replacing within 24hrs with a Rinnai. Hopefully their service will be better should we require it.

I have just bought the 12 litre per minute and find it very sufficient. We are only in a 1 bathroom home but wouldn't suggest this size for a 2+. Its certainly hot enough and you can't beat continuous. Also there is no pilot light so the gas is not always on. Im unaware of gas costs yet to see the efficiency compared to our old heater as we have only just had it installed.

My wife and I have bought a house that has a Rheem integrity 24 already installed.
After our first week we thought there was water problems. Have spent a long time trying to find out what the problem was, but now 1 1/2 years later I've found it constantly cut's out.
Very dissatisfied as purchased my house for a far price as it was supposed to have good quality gear.

Water heater hard to adjust. Its either too cold or too hot. When you get the right temperature, the hot water can go off and you are stranded in cold water. You need to turn off all and turn hot water on again then start over the adjustment. Totally unreliable.

Got a house that came with it.

Just like others, don't consider it and prepare to replace it.

I’ve moved into a property which had this already installed and it’s just not hot enough. It takes ages to heat up then when it finally gets there it’s not hot enough to rinse or wash dishes, soak stains, cleaning, etc. This also impacts greatly on water pressure when using hot water. From a safety perspective I guess it’s a good option, but surely the ability to change the setting would be better.

Worked Ok for 4 years. Usual problem of water taking very long time to heat. Water flow unit has died after 4 years and is a $500 part and $200 to replace. Original unit was only $826. Have decided not to fix based on other reviews here and will look at a better brand to replace with.

This is a great hot water service It is very reliable& as long as you turn on the hot first then the cold it works really great.WE had a bosch before this & it was nothing but TROUBLE & A RIGHT MONGRELL IT COST US A FORTUNE IN PLUMBERS& i would not even buy a BOSH DRILL> BUY A RHEEM YOU CANT GO WRONG; KERRY.
